mc:Ignorable="d"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
Shell:SystemTray.IsVisiable="False" 
Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

Answer 1

There's a typo in your code - you have Shell:SystemTray.IsVisiable="False" try Shell:SystemTray.IsVisible="False" instead...

Answer 2

Based off your XAML tags, you're trying to do this with Windows Phone 8.1 runtime

<Page> was the dead give away.

The shell:SystemTray.IsVisible="True" is only forWindows Phone 8 Silverlight and Windows Phone 8.1 Silverlight
